WEB-REELING- MECHANISM.

Specification of Letters Patent.

Patented Nov. 1o, 190s.

Application led April 4, 1908. Serial No. 425,271.

certain new and useful Improvements inl Web-Reeling Mechanism, of which the-following is a' specification.

This invention relates to web reeling mechanism and has for its object to furnish means for reeling a continuous web of sheet material such as paper, at a uniform tension and at. a rotary speed decreasing in direct prlfportion to .the increase in the size of the ro A In the drawings accom anving this's eciflcation,Figure 1 is a si e elevation o the preferred embodiment of my improvements and Fig. 2 is a plan view of the same.

For the urpose of illustration, I have shown my improvements applied to a machine having rolls 4, 5 for printing, embossing, perforating or the like, the web of paper 10. Said rolls andthe other parts of my Amechanism are mounted in side frames 2, 3.

Roll 1 from which the paper is supplied to the mechanism, is supported on shaft 7 mounted inrearwardly extendin brackets 8, 9 of side frames 2, 3 res ective y. From roll 1 the web 10 passes un er idle roll 11 and thence upwardl between Work rolls 4, 5 and thence forward y between feed rolls 12, 13, to reel shaft 15. Said shaft 15is sup orted for revolution in forwardly-extending rackets 16', 17 of side frames 2, 3 respectively and said shaft has fixed to that. outboard end thereof adjacent to frame 2, disk 14. Said disk is rotated by means of a friction wheel or preferably by two friction wheels 18, 19 on opposite sides respectively thereof. By em loying two friction wheels set opposite eac other,' the disk being gripped therebetween, undue strain on disk 14 is avoided. Said friction wheels 18, 19 are mounted on parallel shafts 20, 21 respectively. arranged parallel with the face of disk 14. Said shafts 20, 21 are slidably supported adjacent to disk 14 in bracket 50 outstanding from frame 2.

Power is communicated to wheels 18, 19 and to the other rotating parts ofmy mechanism assfollows: On stud 22 outstanding 'from frame 3 is rotatably mounted pulley 23 ley 23 is ear 24. Said gear meshes. with gear 25 of ower work roll 5 and said gear 2 5 meshes with gear 26 of upper work roll 4.V Gear 24 also meshes with gear 27 of lower feed roll 13 and said gear 27 meshes'with gear 28 of up er feed roll 12. Shaft 29 of lower feed roll 13 reaches through frame 2 and has fixed to its outboard end adjacent to said frame 2gear 30. Gear 30 in its turn meshes with gear 31 on stud 32 outstanding from frame 2. Fixed to the hub of gear 31 is bevel gear33. Sai-d bevel gear 33 meshes with bevel gear 34 of intermediate shaft '35.'

Said shaft 35 lies parallel with friction wheel' f shafts 2 0, 21 and 1s su ported in bearings 37 outstanding from rame 2.

Power is `communicated from shaft 3 5 to shafts 20, 21 by the following means; 0n;

shaft 35 and driven thereby is gear 38, meshing with gear 39 fixed to the rearward end of shaft 21. Adjacent to gear 39 on shaft 21 is fixed gear 40 meshing with gear 41 fixedon shaft 20. Shafts 20, 21 are actuated to retract wheels 18, 19 toward the peripher of disk 14 and thereby diminish the speed o rotation of said disk as the sizeof roll 10() increases in diameter, by the followin means.:

and by their respective gears41, 40 on the other side of said bracket. Thus when carriage 43 is moved endwise in its guides, shafts 20,21 are carried therewith and correspondingly move endwise through their bearings in bracket 5() and friction wheels 18, 19 have a corresponding radial movement relative to disk 14. Gear 38 is slidable endwise on shaft 35 and is caused to rotate with that shaft by means of key 52 fixed vin said gear and engaging groove 53 in said shaft. Gear 38 has an elon ated hub having a circumferential groove, 51 vtherein for the engagement of dog 54 of bracket 42. By this means said gear 38 is caused to slide endwise on shaft 35 in constant relation to Vbracket 42 and in mesh -with gear 39 on shaft 21.

For actuating carriage 43 to change the, position of wheels 18, 19 `radially relative to disk 14, the following means 1s provided:

From shaft 55, havingibearings in frames 2,

- wheel 59. Similarly supported at t e fortened to the rear end of carriage 43, passes ward end of said frame 2 is s rocket wheel 61. One end of a section of c 4ain 62 is fasover sprocket wheel 59 and the other end thereo is fastened tothe lower end of arm 65. One end of another section of chain 63 is also fastened to the lower end of arm 65, passes up over sprocket 61 and the other end thereof -1s fastened to the front end of carriage 43. vThus as roll 100 increases in diameter by the winding thereon of web 10, governing roll 58 is ,lifted whereby shaft55 is turned on its axis and arm 65 is moved in the direction of its arrow and by means of chain 62 carriage 43 is caused to move backwardly and the points of contact of wheels 18, 19 on disk 14 are moved outwardly relative to the axis of said disk. Said disk is thereby caused to rotate slower and slower in direct proportion with the increase yin size of paper roll 100. v

The gearing of my improved mechanism is usually proportioned so as to drive wheels 18,

19 slightly 1n excess of the required speed of disk 14 so that web 10 is constantly reeled onto roll 100 under tension and by my improvements that tension is always maintained uniform. Furthermore by shifting arm 65 about the axis of shaft 55 relative to arms 56, 57 carrying-roll 58, said tension may be changed as desired. *Furthermore neither the speed of the web feed nor thethickness of the paper affect the operation of my improved mechanism. -When said roll is of the desiredl size it is removed from the machine and governing roll 58'is allowed to drop toward shaft 15 ready to repeat its operation on a new roll 100. By the return movement of roll 58, arm '65 has its direction of movement reversed and by means of chain 63 carriage 43 is returned to its forward position, whereby inner positions relative. to disk 14. a

I claim:

' 1. The combinationof a reel, a'disktherewheels 18, 19 are returnedto their y' on, a friction wheel for driving` said disk, -a

`movable carriage for 'shifting thefriction wheel radially of the disk, means governed by the increase in diameter of the material vwound on the reel for shifting the movable carriage and means for driving the friction'v wheel.

u 2. The combination of a reel, a disk thereon, a friction wheell for. driving said disk, a

mounted for engagement with the material wound on the reel, means for movingthecarriage from the governing roll, vand means for driving the friction wheel.

3. The combination of a reel, a disk thereon, a reci rocating carriage, "a friction Wheel' 65 ymovable carriage for shifting the friction wheel radially of the disk, a governing roll i mounted or rotation on said carriage for engagement with the disk, means operable during the reciprocation of the carriage for rotating the friction wheel, and means controlled by the increase in the diameter of thel mater. rial wound on the reel for moving the reciprocating carriage. l

4. The combination of a reel, a diskthereon, a reciprocating carriage, two friction wheels rotatably mounted thereon and between which the disk is ripped, means for rotating the friction whee s, means governed by the change in diameter of the material ywound on the reel for moving the carriage to shift the friction 'wheels radially-of the disk.V
